摘要

Professional judgment is guided by many inputs; some are subjective, e.g. 'mental models' and some are objective. How accurate are decisions guided by professional judgment, and do the inputs and the way in which they are incorporated into the assessment influence exposure judgment accuracy? Qualitative exposure judgment accuracy, based on subjective inputs is low (mean ～ 30%), motivating the development of a new tool, the "Qualitative Exposure Assessment Checklist Tool", providing objective input to professional judgment. Comprised of 3 heuristics, it is based on physical chemical principles and was refined empirically, through experience. The Checklist provides an ordered approach for applying these principles, and is applicable to volatile and semi-volatile vapor, fiber, aerosol and particulate exposure scenarios. Requiring only four pieces of information: the OEL, vapor pressure of the pure chemical (for vapors), the observed workplace control measures and the 'required level of control', the tool is easy to use and is freely available from the American Industrial Hygiene Association Exposure Assessment Strategies Committee. This influence of this tool on qualitative exposure judgment accuracy was evaluated in a series of workshops in which participants evaluated exposure scenarios, in the absence of personal exposure measurements. Judgments guided by the Checklist were significantly more accurate, ～60 % categorical accuracy, based on the AIHA Exposure Assessment Strategy, and ～ 70% accurate and accurate or overestimating by one exposure control category. The workshop results strongly support the use of this objective tool over other subjective inputs to professional judgment.
